Definitions

  • the present disclosure generally relates to robotic system and method enabling minimally invasive surgery (MIS), and more particularly, to techniques of enhancing robotic surgical procedures with improved interfacing arrangement for maneuvering surgical instrument over the operative area of the patient with enhanced dexterity.
  • MIS minimally invasive surgery
  • Minimally invasive surgical techniques have been adopted worldwide to replace conventional surgical procedures that reduce the amount of extraneous tissue that may be damaged during surgical or diagnostic procedures, thereby reducing the patient recovery time, discomfort, prolonged hospital stays and particularly deleterious side effects.
  • medical robotic systems require a close coupling between the robotic manipulators and the surgical instrument defining the end effectors configured to be delivered through a small percutaneous penetration in a body cavity.
  • the coupling mechanism in surgical robotic systems comprises a driving unit to transfer the controlling motions from the functional end of the robotic arm to the detachably attached surgical instrument and to make the instrument separately sterlizable for use during the course of performing the surgery.
  • the coupling enhances significantly the safety, accuracy, dexterity and speed of minimally invasive and other robotically enhanced procedures.
  • the coupling mechanism has a finite range of motion owing to the arrangement of components on its either side that are configured for transferring electro mechanical signals from the robotic arm to the surgical instrument.
  • the limitation in motion adversely hampers the free movement of the coupling arrangement, so necessitated during the surgery.
  • the robotic arm may have to traverse an undesirable broader course that may enhance probability of potential conflict between said arms.
  • necessitating the presence of driving unit to actualize the motion of the surgical instrument is ostensibly cumbersome, as it creates an additional dependency of the surgical instrument upon the driving unit to be operable, which is uncalled-for, especially in a scenario where the attempt is to make the system flexible and modular to minimize the floor occupancy area, or alternatively enhance the robotic arm mobility area with minimum risk of collision or conflict with other robotic arms.
  • the robotically assisted medical systems utilize a sterile barrier to separate the non sterile robotic arm from the mandatorily sterile surgical instrument operating environment.
  • This sterile barrier often includes a sterile plastic drape that envelops the robotic arm and a sterile adaptor that operably engages with a sterile surgical instrument in a sterile field and non sterile manipulator arm, and includes a flexing drape interface to retain a drape section therebetween such that while the torque and other force feedbacks is received as an input from both the surgical instrument as well as the robotic arm, the sterile barrier is maintained between the sterile surgical instrument and the non-sterile robotic system. Also, the portion of same sterile drape shields the cannula adaptor effectively such that the non exposed portion of adaptor remains sterile.
  • the drape interface if not properly aligned or dressed over the instrument supporting assembly, instrument or cannula adaptors, may get entangled, and interfere with the motion of the surgical instrument.
  • the sterile adaptors disadvantageously involve complex assembly of various intricate components for coupling with corresponding complementary arrangements on the manipulator arm on one side and the surgical instruments on the other, thereby making the whole process costly and cumbersome.
  • a medical robotic system comprising: at least one manipulating arm having a manipulating end; at least one medical instrument; a modular support assembly removably coupled to the manipulating end of the manipulating arm via an intermediate sterlizable fastening component, and adapted to releasably secure thereupon the medical instrument to cause slidable displacement of said instrument independent of the manipulating arm.
  • the modular support assembly is sterlizable and configured to rotate a full 360 degree with respect to the manipulating end.
  • a simplified draping mechanism for maintaining a sterile barrier between the sterile and non-sterile environment is proposed. The mechanism facilitates free unobstructed motion of the manipulating arm, eliminating any over constraint on drape or any twisting thereof with rotary movement of the manipulating end.
  • FIG. 1 illustrates a simplified view of medical robotic system with mounted modular support assembly in accordance with an embodiment of the present invention.
  • FIG. 2( a ) illustrates a cross sectional view of the modular support assembly in accordance with an embodiment of the present invention.
  • FIG. 2( b ) shows a modular support assembly with a tapered trapezoidal bottom for holding the cannula assembly in accordance with one other embodiment of the present invention.
  • FIG. 3 represents a pair of guide rods and a threaded shaft disposed within the modular support assembly in accordance with an embodiment of the present invention.
  • FIG. 4 illustrates an exploded perspective view of the modular support assembly in accordance with an embodiment of the present invention.
  • FIG. 5 illustrates mechanism for securing and sliding the medical instrument along the support assembly in accordance with an embodiment of the present invention.
  • FIG. 6 is an exploded view of the intermediate fastening component in accordance with one embodiment of the present invention.
  • embodiments of the present disclosure are directed to a modular, light weight and sterlizable medical robotic system for performing a tele-robotic minimally invasive surgery (MIS).
  • the medical robotic system generally includes one or more articulated arms, exact number dependent on the type of medical or surgical procedure to be performed among many other factors.
